Final answer:
The percent of decrease is approximately 28%.
Step-by-step explanation:
To find the percent decrease, we need to calculate the difference between the number of incidents of vandalism last year and this year, and then divide it by the number of incidents last year. Finally, we multiply the result by 100 to get the percentage.
The formula for percent decrease is:
Percent Decrease = ((Original Value - New Value)/Original Value) * 100
Plugging in the values from the question, we get:
Percent Decrease = ((32 - 23)/32) * 100 = (9/32) * 100 = 28.125%
Rounding to the nearest percent, the percent decrease is approximately 28%.
